This book is devoted to the theoretical and experimental investigation of the optoelectronic oscillator (OEO) with direct and external modulation of laser emission. Such devices, sources of precision radio frequency oscillations using laser excitation, are novel and technologically relevant, with manifold possible applications. The book includes a review of the present state of the theory and generation techniques in microwave and mm-wave ranges for traditional and optoelectronic oscillators, description of OEO construction and operation principles, theoretical oscillation analysis and mathematical description of the relevant semi-classical laser physics, and investigation of the power spectral density of noises. Technical features and advantages of OEOs with external and direct modulation of laser emission are discussed together with functional diagrams. The characteristics of OEOs are compared with other traditional RF oscillators, such as quartz, surface acoustic waves, and oscillators with electromagnetic wave cavities. Special attention is paid to Q-factors and phase noises of RF carriers at small offsets. The authors discuss the technical characteristics of modern optoelectronic methods for precision RF oscillation formation, such as commercial large-dimension and compact quantum frequency standards with optical pumping on cesium and rubidium cells. This book is aimed at scientists and engineers in academia and industry who work with sources of microwave and mm-wave signals.

Focuses on non-traditional optoelectronic oscillators (OEO) featuring a laser or quantum well laser diode Considers in depth the sources of phase noises and their minimization Employs a semi-classical model for the laser description for a simpler yet still insightful treatment of phase noise

After graduation of Ph.D. course and defending a Ph.D. thesis in 1986, he worked on Department of Performing of Oscillations and Signals in Radio Engineering Faculty of MPEI. At the same time, he was with SIMVOL Ltd. Company in Moscow, Russia. Here he led the pioneering works on the creation of Optoelectronic Oscillators and Magneto-Infrared Laser Diode Therapeutic devices. Since 1997, he was with OPTEN Ltd. Company in Moscow, Russia. Here he worked as a Department of Education Programs manager until 2005. At the same time, he was engaged in creating, organizing, and conducting courses in Russia and the United States of America (USTTI) of advanced training for senior engineering personnel of electric power companies in Russia and a number of countries. These courses were devoted to the technology of laying fiber-optic communication cables overhead the phase wires of long-height high-voltage power lines. From 2005 to the present time he works as a freelancer scientist. His academic experience spans over 30 years. He worked as assistant professor, senior teacher and associate professor.
